This invention relates to apparatus-dor bending rods and theobject of the inven` tionis toprovide a simple manually operated device for bending rods for building -con- 'struction to U shape as used for beam hangers andthelike.` t.

' In the drawings Fig..1'is alpejrspective View of my apparatus withf a pile of rods in place ready for the first bending operation. Fig. 2 is *an enlargedc'ross section of the aparatus as seen Jfrom the line 2-2 of Fig. 1. Fig. 3 isk an Venlarged section through the side frame member of the apparatus as. seen from the line 3 3 of Fig. 1.

In further detail the apparatus comprises a frame having longitudinal side pieces 1 irrnly securedto cross members 2 and 3, and slidable'base plates l and 5. f 7 i Base 5 carries a Vertical plate 6 for aligning v I20 the ends' of a pile of rods k7 aligned one'over thevother between uprights 8 carried on base 3, and further aligned between posts 9 and 10 carried bybase 4i. Posts9 and 1() are4 locked together on top to prevent spreading open v2.5y by means of a Aflat bar 11fhinged at 12 to one of the posts, engagingfa slot 13 in the other post and held by a nut 14 whereby the bars may be clamped in place if required.y

End base 5 may be setat various points i along the frame by means of bolts 15 iitting into any ofthe holes 16.4

The rods extend forwardly beyond posts 9 and 10 and reston a rail 17. which curves around on top of framemember 1 to extend! therewith for a distance as shown in parallel Fig. 1 and which rail takes the weight of the stack of rods during the bending operation.

To bend the rods I provide a yoke 18v I pivoted at 19 to the forward sidel of post 10 403 and itted with a vertical'roller 2() arranged to contact the side of the stack of rods, while' a lever handle 21 projecting forwardly from y the yoke provides means whereby any operative may swing the yoke in direction of the arrows tothereby carry the roller in ContactA with the rods' and bend all simultaneously to the dotted position 7.

After the first bend, stop .side rail 1 of rameby pulling out pin 23 50y and moved toward the rear of the frame the yto a heavy 272 is released from required. :distance'for the bend `desire-dv andl its p indropped through one of the holes 24 provided, andv the base Ll-slid alongy un'tilit strikesthe stop, and after which the bending operation is, repeated to form the return y or: U bend.

Andadditional locking pin' is iirbasety which maybe droppedthroughvv holesofthefram'e.: .i i Post Qis roundedor has yits leftehand:con-
